Video: NXTLiftBoy Has done it again!!!

snowblader13 — Mon, 14 Apr 2008 03:29:50 +0000

Well even though this is not an NXT Creation I think it is still awesome. As most of you know NXTLiftBoy has made several really cool creations. You can check them out over at MOCpages Here.

Here is what he has to say about it:

The ChainRider is a trike featuring two huge wheels, remote control, and, i dare say, excellent drive properties. It is made entirely from a single LEGO set 8275, but appears to be much more fun in playing than the bulldozer!

For more information and building instructions see: http://www.mocpages.com/moc.php/54200

I challenge anyone to try to make a similar version of this with an NXT at the control.

NXT Connect 4 Robot

snowblader13 — Wed, 09 Apr 2008 09:00:48 +0000

Here is a pretty cool project that Sascha from Germany Sent me.

Here is the information from Sascha:

“This is the Lego NXT “4 In A Row” robot project.
This robot is able to play against you on itself.
He is independend of any computer, so the program – programmed with NXC – is running on the NXT brick.
The human player can choose the row while pushing the touch sensor as often as the row’s number. The computer decides on its own, which row would be the best for it.
This KI is working mainly on the MINIMAX algorithm. However the computer is not as hard as i want him to be, because of the less NXT Brick speed.
the algorithm works like that: The computer simulates the next 3 possible steps and gives any game situation a specific number of points. The Row with the most points will be the next computers choice.
The robot uses three NXT motors:
- one is moving the gameboard
- the second fixes the stones
- the third opens the gate”

“Lonesome George”, a turtle robot

Mini_Man176 — Mon, 31 Mar 2008 19:48:40 +0000

Hi guys, I’m a new contributor and for my first post I’m going to post my latest project, “Lonesome George”. It’s named after a turtle on the Galapagos Islands. Lonesome George drives (not walks) forwards and backwards (but it doesn’t turn). Its shell is made of cardboard but it’s still entirely LEGO because the box is made by LEGO! When it sees something it will go into its shell and pull the ultrasonic sensor down.

I will post a program and LDD file soon.

Giganto

ro1000 — Fri, 07 Mar 2008 15:00:28 +0000

Giganto is a joint effor of several people I know and me. It uses two XL PF motors, several NXT motors, and two NXTs. This is it’s second version, and while it is still not THAT big it’s alot bigger than many robots I have built so far. See more of it on NXTLog Here:

And by the way, the Lego Technic Bulldozer I bought came in the mail today, so some of my upcoming projects are going to have a obvious size difference than my old ones!

MINDSTORMS NXT Biped Building Challenge

snowblader13 — Wed, 05 Mar 2008 01:26:38 +0000

Here is the Newest NXTLOG building challenge:

From NXTLOG:

“These robots are made for walkin’

Alpha Rex can’t be the only biped you’ll ever make, so we’re asking you to create the NXT two legged walker!

Bipeds are said to be the most difficult robot to make, but we know NXTLOGgers are up for the challenge!

All entries to NXTLOG fall under the Terms of Service

Entries must be submitted from Saturday March 1, 2008 – Monday March 31, 2008

All entries must be tagged “NXT200803″

Only LEGO elements may be used.

There is no limit on the amount of LEGO MINDSTORMS NXT sensors, motors, NXT programmable bricks, HiTechnic sensors, or Bluetooth communication. No home brewed sensors allowed.

A programmable LEGO MINDSTORMS NXT brick must be onboard the robot and must control the robot’s actions.

The NXT robot must be a robot that can take still pictures with a camera and you must explain how the robot is a “Biped” robot in your NXTLOG documentation.”

To see the rest Click HERE.

There are already several Bipeds Out there so get creative and come up with soothing awesome!!!

ATC – (A)ll (T)errain (C)rawler

NXTMonger — Tue, 26 Feb 2008 15:00:54 +0000

This is a sturdy little robot that I made a while ago that can get over anything. Well, not exactly, but it can get over dictionaries! It has 4 treads that can pivot freely, enabling it to have great traction when driving over books etc. Here’s the movie:

SumoBot v2

NXTMonger — Mon, 25 Feb 2008 20:05:12 +0000

Here it is… my latest creation worth publishing! It’s a sumo bot that was for the NXTLOG sumo challenge that as usual I missed due to the deadline being a couple months before I made this. Oh well, at least I can still post it here! So, pretty much what’s cool about it is traction. It has 6 wheels that give it awesome traction. The only disadvantage is that it drives kind of slowly, but if it collides with the opponent boy are they going down! The program isn’t really worth posting because it just has the robot stay on the table. There is no ultrasonic sensor to seek the opponent because due to limited space in my LEGO room (AKA bedroom) It would detect my dresser and attack it Pictures here.

PPS – Ping Pong Shooter

NXTMonger — Sun, 24 Feb 2008 16:54:51 +0000

Hello, I’m NXTMonger, and I would hate to have a post just telling you who I am so here’s one of my projects: It’s called PPS – Ping Pong Shooter. It has a magazine of about seven ping pong balls and can shoot them out quite fast. In the video it’s remote controlled by me.

Can you Guess What I am?

snowblader13 — Fri, 22 Feb 2008 15:00:11 +0000

This is my newest creation that I am currently working on. (Well actually one out of three that I am. HeHe) This is just the first stage of this project, Because it was a little too late at night to continue it. Like all things it will have to be ripped apart and rebuilt so that it is stronger and can support ALOT more weight. This project will use an NXT for its Propulsion and other functions

I am going to make 2 versions of this for similar yet different purposes.

Judging from the pictures can you guess what I am going to be used for? Like I had stated above there are going to be 2 variations of this used for a similar purpose but different at the same time.

One will be for… And the other for…

Leave a comment for what you will think it will be used for.

Answer

Well after somebody guessed what it is for I decided to give you guys the answer. Airkraft guessed:

“Is it to run through some kind of a track? maybe one version for the horizontal movement, and another for the vertical one?

The track would fit between two close sets of wheels.

Air”

I wanted to make some sort of overhead tram system that could be used as a crane, I had some PVC pipe leftover from another project so I went about making a set of wheels that fit over the pipe nice and tight. I only have a 16 inch piece but I am going to get some more and make a large section that goes over my desk and be to the other side of my room. This is so I can take stuff from my desk to the floor, hoping that the pipe and tram are strong enough. I also hope that it is strong enough to be able to climb up the pipe vertically, from preliminart tests I believe that it can. Here are some initial pictures of it on a pipe.
